You are right, there is differences between iOS & Android platform. I am working on a cross-platform app and discovering these issues 
If it is possible for App Inventor to hide these differences, this is great, but I understand it may be difficult or impossible.@ewpatton Do you think this mismatch could be hidden?
I am already testing on which platform the app is running:
What could be good would be to share such discripancies (one other issue is the LatitudeFromAdress: LatitudeFromAddress not working with iOS) in order to help us develop cross-platform app and share our experiences (and help people facing the same pb in the future)
Is it something that could be added on iOS implementation web page: https://doesappinventorrunonios.com/ or a dedicated web? blog could be created?
Thanks for your feedback
